Introduction to Tiaoshi Street: Built during the Kangxi period, the ancient Tiaoshi Street runs parallel to the canal from north to south and has a history of more than 300 years. The stone street is less than 2.5 meters wide and 1,500 meters long. It is paved with a single piece of blue stone, criss-crossing in the middle, with a brick underwater channel underneath, vertical stones on both sides, and a shade and ditch. . There are round gates at the north and south ends of the street, with watchtowers and wooden fences on them. They are very simple and spectacular. The two round gates in the north and south are the only way for Nanxiang and Beixiang residents to enter the town.
